贺兰山东麓是国内外公认的酿酒葡萄最佳产区之一，属于世界优质酿酒葡萄种植的"黄金地带"。目前，该地区酿酒葡萄种植面积已达44万亩，占全国总种植面积的30%，位列国内第一。虽然贺兰山东麓地区有着发展酿酒葡萄产业的独特优势，种植面积在逐年扩大，但是，由于位居西北内陆，春季冷空气活动频繁，该地区的晚霜冻危害严重，严重制约着酿酒葡萄产业发展。开展精细化的、专门性的酿酒葡萄晚霜冻预报的需求极为迫切。项目计划利用室内模拟实验、大田试验和数理统计模拟等方法，研究并确定贺兰山东麓地区酿酒葡萄主栽品种春季不同发育期的霜害阈值，建立酿酒葡萄生长发育预测模型，修订并完善贺兰山东麓最低气温预报方法。在此基础上，建立贺兰山东麓酿酒葡萄晚霜冻预报技术流程。项目的实施，可明显提升酿酒葡萄霜冻灾害专业预报能力，对于提升酿酒葡萄霜冻防御能力，减轻霜冻灾害损失，保障贺兰山东麓地区酿酒葡萄产业的健康发展具有重大的现实意义。

The eastern HeLan mountain is one of the best wine grape producing areas and "gold planting zone"recognized at home and abroad. At present, the area of wine grape planting area has reached 30000 h㎡, accounted for 30% of the total planting area in China, ranked first in domestic. Although the eastern Helan mountain has unique advantage in development of wine grape industry, planting area has been expanding constantly，but some natural disasters have be districting factors，for example late frost. Because of spring cold air activity， late frost often bring huge loss to wine grape industry in the eastern HeLan mountain.To carry out special wine grape frost forecast is urgent social demand of the meteorological department. Using the Laboratory experiment, field test and statistical simulation , the project plans to study and determine frost damage threshold of different growth periods of wine grape，establish phonological period forecast model of wine grape， revise and perfect the lowest temperature forecast method in the eastern HeLan mountain. On this basis, late frost forecasting technical process of wine grape would be established. The implementation of the project, can significantly enhance the frost grape forecast ability, to promote the wine grape frost defense capability, reduce the frost disaster losses. This project is of great significance to ensure the healthy development of the wine grape industry in the eastern HeLan mountain.
